DETAILED DESCRIPTION OF EMBODIMENTS

Selected embodiments will now be explained with reference to the drawings. It will be apparent to those skilled in the art from this disclosure that the following descriptions of the embodiments are provided for illustration only and not for the purpose of limiting the invention as defined by the appended claims and their equivalents.

Referring initially to FIGS. 1 and 2, a passenger compartment 10 of a vehicle, the passenger compartment including an instrument panel 12 and a trim panel 14, is illustrated in accordance with a first embodiment.

The passenger compartment 10 is defined within a vehicle body structure that includes, among other things, a floor 20 and a front wall 22. The instrument panel 12 is fixedly attached to the front wall 22 of the vehicle 10 (e.g., via a cross-car beam—not shown) in a conventional manner. A center console 24 is attached to the floor 20 in a conventional manner and extends rearward from a central region of the instrument panel 12. An airbag 26 is also fixedly coupled to the front wall 22 by structural elements (e.g., via the cross-car beam—not shown) in a conventional manner. The structural elements (not shown) can be directly fixed to the front wall 22 or to the cross-car beam (not shown) and hidden from view by the instrument panel 12. It should be understood from the drawings and the description herein that there can be multiple airbags within the passenger compartment 10 of the vehicle. However, the airbag 26 has at least a peripheral relationship to the features of the trim panel 14. Therefore, only the airbag 26 is identified within the passenger compartment 10 for purposes of understanding the various features of the invention.

The instrument panel 12 is an interior assembly of the passenger compartment 10. The instrument panel 12 basically includes at least one frame portion 30 (shown in FIG. 3), a driver's side section 32, a central section 34, a passenger's side section 36, and two of the trim panels 14. The instrument panel 12 further includes various conventional panels and conventional components provided throughout the driver's side section 32, the central section 34 and the passenger's side section 36 that are not identified or described for the sake of brevity.

The frame portion 30 is an interior part (shown in FIG. 3) that is mounted and/or supported within the passenger compartment 10 in a conventional manner. For example, the frame portion 30 can be fixed to the front wall 22 or the cross-car beam by fasteners (not shown). The frame portion 30 can include a metal frame, a composite frame and/or molded plastic or polymer elements as needed and desired. In other words, the frame portion 30 can have any of a variety of shapes and forms, depending upon the overall design of the passenger compartment 10 and instrument panel 12, and is not limited to the schematic representation shown in FIGS. 3 and 4.

The frame portion 30 includes an outer shell with an inner surface 40, an outer surface 42 and a plurality of mounting sections, such as a first mounting section 44, a second mounting section 46, a third mounting section 48 and lower mounting sections 50, 52 and 54. Each of the mounting sections 44, 46, 48, 50, 52 and 54 defines a corresponding mounting opening or mounting hole that extends from the inner surface 40 to the outer surface 42. More specifically, as best shown in FIGS. 3-5, the first mounting section 44 defines a mounting hole 44 a, the second mounting section 46 defines a mounting hole 46 a and the third mounting section 48 defines a mounting hole 48 a. As shown in FIGS. 3 and 4, each of the lower mounting sections 50, 52 and 54 define respective mounting holes 50 a, 52 a and 54 a.

The frame portion 30 includes various other conventional mounting portions (not shown) for supporting the various elements and components of the instrument panel 12, description of which is omitted for the sake of brevity. Further, sections of the outer surface 42 of the frame portion 30 can also include a decorative outer covering made of textile, leather, wood veneer, and/or other materials depending upon design of the passenger compartment 10.

As shown in FIG. 3, the first mounting section 44 extends along a plane P₁, while the second and third mounting sections 46 and 48 extend along a plane P₂. The plane P₁ and plane P₂ are spaced apart from one another in the vicinity of the first, second and third mounting sections 44, 46 and 48. As well, the mounting hole 44 a defined by the first mounting section 44 extends from the inner surface 40 to the outer surface 42 in a direction perpendicular to the plane P₁. The mounting hole 46 a defined by the second mounting section 46 extends from the inner surface 40 to the outer surface 42 in a direction perpendicular to the plane P₂. The mounting hole 48 a defined by the third mounting section 48 extends from the inner surface 40 to the outer surface 42 in a direction perpendicular to the plane P₂.

As shown in FIGS. 1 and 2, the driver's side section 32 of the instrument panel 12 includes a steering wheel W and an instrument display 60. The central section 34 includes an audio system control section 62 and an air conditioning control section 64. The passenger's side section 36 includes a glove box 66 and an airbag panel 68. The airbag panel 68 is supported to the frame portion 30 (a vehicle interior part) concealing the airbag 26. As shown in FIGS. 1 and 2, the airbag panel 68 is positioned adjacent to the passenger's side trim panel 14.

During the assembling process where the various elements of the instrument panel 12 are assembled, elements such as the airbag 26, the instrument display 60, the air conditioning control section 62, the audio system control section 64, the glove box 66 and the airbag panel 68 are all installed prior to installation of the trim panels 14. In other words, in the depicted embodiment, the final installation elements of the instrument panel 12 are the two trim panels 14.

There are two trim panels 14. The trim panels 14 are identical except that they are symmetrical mirror images of one another. Alternatively, the trim panel 14 on the driver's side can differ from the trim panel 14 on the passenger's side, depending on the airbag configuration in the instrument panel 12. For purposes of understanding the invention, description of only one of the trim panels 14 is necessary. As such, the description below applies equally to both trim panels 14. In the description below, only the trim panel 14 located on the passenger's side of the instrument panel 12 is described.

The trim panel 14 is preferably made of a molded plastic material that includes a decorative surface 70 and a hidden backside surface 72. The decorative surface 70 can include a separate, attached textile covering, a leather covering, a wood veneer, and/or the like. Alternatively, the decorative surface 70 can be provided with a textured contour, depending upon the overall design and appearance of the instrument panel 12.

As shown in FIGS. 6 and 7, the backside surface 72 of the trim panel includes a plurality of projections that extend therefrom. More specifically, the trim panel 14 is formed or molded integrally as a one piece element with the plurality of projections being integrally formed therewith. The plurality of projections include a first projection 80, a second projection 82 and third projection 84 all located at an upper end of the backside surface 72 of the trim panel 14. Below the upper end, the plurality of projections of the trim panel 14 further includes a fourth projection 86, a fifth projection 88 and a sixth projection 90. The trim panel 14 also includes a separately attached first clip 100 and a plurality of separately attached second clips 102 that are described in greater detail below.

As shown in FIGS. 8 and 9, the first projection 80 is an elongated cantilevered portion of the trim panel 14. The first projection 80 extends from the backside surface 72. As is indicated in FIG. 8, the first projection 80 does not extend in a direction parallel to either of the second and third projections 82 and 84. Rather, the first projection 80 is slightly inclined or angularly offset from a direction parallel to the second and third projection 82 and 84. As shown in FIG. 9, the first projection 80 includes a dimple or depression 80 a on an upper surface thereof.

The first clip 100 is attached to a distal end of the first projection 80, as indicated in FIGS. 8 and 9. As shown in FIGS. 10-13, the first clip 100 includes a pair of clamping portions 100 a dimensioned to fit to a distal end of the first projection 80, and a hook end that defines a first restricting portion 100 b. Each of the clamping portions 100 a is provided with a barb (a deformed area) or tab 100 c. The dimple or depression 80 a on the upper surface first projection 80 is dimensioned to receive both of the tabs 100 c of the first clip 100. When the first clip 100 is installed to the end of the first projection 80, the clamping portions 100 a fit around sides of the distal end of the first projection 80 and the tabs 100 c snap fit and extend into the depression 80 a, locking the first clip 100 to the first projection 80. Attempts to remove the first clip 100 from the first projection 80 cause the tabs 100 c to dig into the surface of the first projection 80 in the area around the depression 80 a, further fixing the first clip 100 to the first projection 80.

As is shown in FIG. 8, the first projection 80 also includes a downwardly extending stopper block that defines a second restricting portion 80 b. The second restricting portion 80 b is formed integrally with the first projection 80 and the trim panel 14. The second restricting portion 80 b extends in a direction transverse to an insertion direction of the first projection 80, as described in greater detail below. Further, the first restricting portion 100 b further extends in a vehicle upward direction and the second restricting portion 80 b extends in a vehicle downward direction.

As shown in FIG. 16, the first projection 80 has an upper surface 80 c and a lower surface 80 d. The upper and lower surfaces 80 c and 80 d contact adjacent surfaces of the mounting hole 44 a of the frame portion 30 of the instrument panel 12 such that vertical movement of the trim panel 14 relative to the frame portion 30 of the instrument panel 12 is restricted with the trim panel 14 in the installed position (shown in FIGS. 4 and 16).

The insertion direction of the first projection 80 is defined as the direction of movement of the first projection 80 during installation into the mounting hole 44 a of the first mounting section 44 of the frame portion 30 of the instrument panel 30. The insertion direction is indicated by the arrows A in FIG. 3. The arrows A indicate the movement of each of the projections 80, 82, 84, 86, 88 and 90 as they move from an uninstalled position adjacent to the instrument panel 12 (FIG. 3) to an installed position (FIG. 4).

As shown in FIG. 8, the second projection 82 includes a hook that defines a third restricting portion 82 a. The third restricting portion 82 a extends in a vehicle downward direction from the second projection 82. As shown in FIGS. 3 and 4, the second projection 82, the fourth projection 86, the fifth projection 88 and the sixth projection 90 all extend in directions parallel to one another. Hence, the first projection 80 is angularly offset relative to each of the second projection 82, the fourth projection 86, the fifth projection 88 and the sixth projection 90. In other words, the first projection 80 is not parallel to any of the second projection 82, the fourth projection 86, the fifth projection 88 and the sixth projection 90.

As is also shown in FIG. 8, the first projection 80 has a first length L₁ measured from a support surface 72 a of the trim panel 14 to a distal end of the first projection 80. The second projection 82 has a second length L₂ measured from the support surface 72 a of the trim panel 14 to a distal end of the second projection 82. The first length L₁ is greater than the second length L₂.

The second projection 82 is also provided with one of the plurality of second clips 102. As shown in FIGS. 14 and 15, the second clips 102 each include inner attachment tabs 102 a and outwardly extending attachment projections 102 b. Similarly, each of the fourth projection 86, the fifth projection 88 and the sixth projection 90 are also provided with one of the plurality of second clips 102. The second clips 102 mount to respective distal ends of the second projection 82, the fourth projection 86, the fifth projection 88 and the sixth projection 90, as shown in FIGS. 3, 4, 6 and 7. The inner attachment tabs 102 a of the second clips 102 are arranged to clamp on to respective distal ends of the second projection 82, the fourth projection 86, the fifth projection 88 and the sixth projection 90 in a conventional manner.

FIG. 4 shows the trim panel 14 installed to the frame portion 30 of the instrument panel 12. As shown in FIG. 4, the second projection 82, the fourth projection 86, the fifth projection 88 and the sixth projection 90, retain the trim panel 14 in an installed position against the frame portion 30 of the instrument panel 12. More specifically, in the installed position, the outwardly extending attachment projections 102 b of respective ones of the plurality of second clips 102 contact and engage surfaces of the frame portion 30 that define the mounting holes 46 a, 50 a, 52 a and 54 a, thereby retaining the trim panel 14 in the installed position. The outwardly extending attachment projections 102 b are compressed between lateral surfaces of the corresponding mounting hole when installed to the mounting holes 46 a, 50 a, 52 a and 54 a. For example, when the second projection 82 is installed to the mounting hole 46 a of the second mounting section 46, the attachment projections 102 b of the second clip 102 contact and press against lateral sides 46 b of the mounting hole 46 a (see FIG. 5). The outwardly extending attachment projections 102 b provide an outward biasing force when installed. Therefore, once installed, the outwardly extending attachment projections 102 b retain the plurality of second clips 102 (and respective ones of the second projection 82, the fourth projection 86, the fifth projection 88 and the sixth projection 90) within the mounting holes 46 a, 50 a, 52 a and 54 a. In other words, the second clips 102 retain the trim panel 14 in the installed position relative to the instrument panel 12. Since the second clips 102 are conventional elements and their usage in installing trim components within vehicles is well known, further description is omitted for the sake of brevity.

As is explained in greater detail below, the first projection 80 and the third projection 82 are not required to hold or retain the trim panel 14 in the installed position against the frame portion 30 of the instrument panel 12. Rather, the first projection 80 and the third projection 82 retain the trim panel 14 from being completely detached from the instrument panel 12 when the airbag 26 deploys, as explained below after a description of the third projection 84.

The third projection 84 extends from the backside surface 72. A bottom surface 84 c of the third projection 84 extends in a direction that is approximately parallel to the second projection 82. The third projection 84 includes a distal end 84 a and an upwardly extending protrusion that defines a fourth restricting portion 84 b. The fourth restricting portion 84 b is located proximate a mid-section of the third projection 84, spaced apart from the distal end 84 a of the third projection 84. The third projection 84 is angularly offset from both a vertical direction and a horizontal direction with the trim panel 84 in the installed position.

As shown in FIG. 16, each of the first, second and third projections 80, 82 and 84 extends generally in an insertion direction from the backside surface 70 of the trim panel 14 through the respective mounting holes 44 a, 46 a and 48 a of the first, second and third mounting sections 44, 46 and 48 of the frame portion 30, except that the first projection 80 is angularly offset from a direction parallel to the second and third projections 82 and 84. In the installed position (FIG. 4): the first projection 80 extends into the mounting hole 44 a of the first mounting section 44; the second projection 82 extends into the mounting hole 46 a of the second mounting section 46; and, the third projection 84 extends into the mounting hole 48 a of the third mounting section 48. Each of the first, second and third projections 80, 82 and 84 includes at least one restricting portion that retains the trim panel 14 from being completely detached from the instrument panel 12 upon deployment of the airbag 26.

As shown in FIG. 16, the restricting portions of the first, second and third projections 80, 82 and 84 are spaced apart from an adjacent section of the inner surface 40 of the frame portion 30 of the instrument panel 12 by differing respective distances. Specifically, the first restricting portion 100 b of the first projection 80 defines an abutment surface A₁ facing the first mounting section 44. The abutment surface A₁ of the first restricting portion 100 b is spaced apart from the inner surface 40 at the first mounting section 44 by a first distance D₁. The second restricting portion 80 b of the first projection 80 defines an abutment surface A₂ facing the first mounting section 44. The abutment surface A₂ of the second restricting portion 80 b is spaced apart from the inner surface 40 at the first mounting section 44 by a second distance D₂. The third restricting portion 82 a of the second projection 82 defines an abutment surface A₃ facing the second mounting section 46. The abutment surface A₃ of the third restricting portion 82 a is spaced apart from the inner surface 40 at the second mounting section 46 by a third distance D₃. Finally, the fourth restricting portion 84 b of the third projection 84 defines an abutment surface A₄ facing the inner surface 40. The abutment surface A₄ of the fourth restricting portion 84 b is spaced apart from the inner surface 40 at the third mounting section 46 by a fourth distance D₄.

As shown in FIG. 16, the first distance D₁ is greater than the second distance D₂, the second distance D₂ is greater than the third distance D₃, and the third distance is greater than the fourth distance D₄. In other words, the first restricting portion 100 b, the second restricting portion 80 b, the third restricting portion 82 a, the fourth restricting portion 84 b are located at differing positions relative to contact portions of the inner surface 40 where the first restricting portion 100 b, the second restricting portion 80 b, the third restricting portion 82 a, the fourth restricting portion 84 b could possibly contact the inner surface 40 when the trim panel 14 becomes detached.

Each of FIGS. 17, 18, 19 and 20 shows the trim panel 14 in a different restrained position in response to the trim panel 14 moving after deployment of the airbag 26. Each restrained position represents a differing one of the first restricting portion 100 b, the second restricting portion 80 b, the third restricting portion 82 a, the fourth restricting portion 84 b restricting further movement of the trim panel 14 after detachment.

More specifically, in a circumstance where the airbag 26 deploys, the airbag panel 68 (shown FIGS. 1 and 2) will at least partially detach from the instrument panel 12, allowing the airbag 26 to inflate and expand to protect the vehicle passenger. It is also possible for the trim panel 14 to additionally be dislodged from the installed position as a result of deployment of the airbag 26. If the trim panel 14 does become dislodged from the installed position relative to the instrument panel 12, one or more of the first, second, third and fourth restricting portions 100 b, 80 b, 82 a and 84 b retains or restrains the trim panel 14 from being completely detached from the instrument panel 12.

For example, as shown in FIG. 17, in the event that the trim panel 14 becomes dislodged by an airbag deployment event where the trim panel 14 is moved upward and/or rearward relative to the instrument panel 12, the trim panel 14 can move the first distance D₁ until the first restricting portion 100 b contacts an upper region of the first mounting section 44, along the inner surface 40 of the frame portion 30. It should be noted that the first restricting portion 100 b is at least a portion of a deflectable part of the first clip 100 that is cantilevered with respect to the first projection 80. Further, the first restricting portion 100 b (the deflectable part) basically forms an abutment that contacts the inner surface 40 upon the trim panel 14 being moved by the first distance D₁ (a first prescribed deployment distance) from the installed position to the restrained position depicted in FIG. 17.

As shown in FIG. 18, in the event that the trim panel 14 becomes dislodged by an airbag deployment event where the trim panel 14 is moved rearward and/or downward relative to the instrument panel 14, the trim panel 14 can move the second distance D₂ until the second restricting portion 80 b contacts a lower region of the first mounting section 44, along the inner surface 40 of the frame portion 30.

As shown in FIG. 19, in the event that the trim panel 14 becomes dislodged by an airbag deployment event where the trim panel 14 is moved downward and/or rearward relative to the instrument panel 14, the trim panel 14 can move the third distance D₃ until the third restricting portion 82 a contacts a lower region of the second mounting section 46, along the inner surface 40 of the frame portion 30. It should further be noted that the second clip 102 is an attachment portion that attaches the trim panel 14 to the instrument panel 12. Hence, the third restricting portion 82 a and the second clip 102 (an attachment portion) are disposed on a common one of the plurality of projections.

Finally, as shown in FIG. 20, in the event that the trim panel 14 becomes dislodged by an airbag deployment event where the trim panel 14 is moved upward and/or rearward relative to the instrument panel 14, the trim panel 14 can move the fourth distance D₄ until the fourth restricting portion 84 b contacts an upper region of the third mounting section 46, along the inner surface 40 of the frame portion 30. It should be noted that the third projection 84 is a deflectable part that deflects in a direction transverse to the insertion direction (arrow A) of the first, second and third projections 80, 82 and 84 during installation to the frame portion 30.

Thus, the trim panel 14 is provided with four differing types restricting portions, each able to retain the trim panel 14 from being completely detached from the instrument panel 12 during or after airbag deployment. Further, the four differing types of restricting portions provide multiple levels of retention such that if the trim panel 14 becomes dislodged from the installed position depicted in FIG. 4, regardless of the direction of the dislodging momentum, one or more of the first restricting portion 100 b, the second restricting portion 80 b, the third restricting portion 82 a and the fourth restricting portion 84 b contacts the inner surface 40 of the frame portion 30 and prevents the trim panel 14 from becoming completely detached from the instrument panel 12.

The trim panel 14 is easily installed and removed from the instrument panel 12, in spite of the inclusion of the first restricting portion 100 b, the second restricting portion 80 b, the third restricting portion 82 a and the fourth restricting portion 84 b.

To install the trim panel 14, the first projection 80 is first installed until the first restricting portion 100 b snap fits into the mounting hole 44 a, as shown in FIG. 17. Using the first restricting portion 100 b as a pivot point for leverage, the installer then pivots the trim panel 14 about the contact point between the first restricting portion 100 b and adjacent section of the inner surface 40. By pushing the trim panel 14 gently upward, the second projection 82 and the third restricting portion 82 a can move through the mounting hole 46 a. Continued movement in the installation direction can continue until the third projection 84 deflects in response to contact with the upper surface of the mounting hole 48 a of the third mounting section 48. At a point of substantial deflection of the third projection 84, the fourth restricting portion 84 b can be inserted into the mounting hole 48 a. The trim panel 14 is then pushed into place causing the plurality of second clips 102 to snap fit into respective mounting holes 46 a, 50 a, 52 a and 54 a.

To remove the trim panel 14, the above process is reversed, by initially pulling the second clips 102 out of their snap fit positions, angling the trim panel 14 upward such that a bottom end thereof is moved away from the instrument panel 12. The third projection 84 is then intentionally deflected in order to allow the fourth restricting portion 84 b to move out of the mounting hole 48 a. Once the fourth restricting portion 84 b has cleared the mounting hole 48 a, the trim panel 14 is moved upward slightly to allow the third restricting portion 82 a to be moved out of the mounting hole 46 a. Thereafter, simple upward, outward and then downward movement of the trim panel allows the second restricting portion 80 b and the first restricting portion 100 b to come out of the mounting hole 44 a.

The above described series of upward and downward movements necessary to install and remove the trim panel 14 from the instrument panel 12 demonstrate the complex series of movements necessary to free the trim panel 14. Thus, during a typically instantaneous airbag deployment event, if the trim panel 14 becomes dislodged, one or more of the first restricting portion 100 b, the second restricting portion 80 b, the third restricting portion 82 a and the fourth restricting portion 84 b will restrain the trim panel 14 against complete removal from the instrument panel 14 without the need of a separate tether or tethering device.

The various sections of the passenger compartment 10 and the instrument panel 12 other than the trim panel 14 are conventional components that are well known in the art. Since these features are well known in the art, these structures will not be discussed or illustrated in detail herein.
